12 Claims.

This invention relates to and has for an object the provision of an improved type of extractor cover formed of flexible material, of circular shape, reinforced at its outer edge and its central portion so as to provide ample rigidity and strength for supporting the cover in operative position during the rapid rotation of the extractor, and yet sufciently flexible so as to render the cover more readily attachable and detachable.

A particular object of the invention is to provide a circular cover with a central opening therein and a radial slit extending from said opening to the outer edge with overlapping flaps, together with means for reinforcing the cover so that the necessity for buckles or other fastenings at the flaps is eliminated.

Other objects will appear as the description progresses.

In the accompanying drawings I have shown a preferred form of extractor cover embodying my improvements, in which Fig. 1 is a top plan view.

Fig. 2 is a fragmentary sectional elevation of an extractor such as is used in laundries with my improved cover in operative position thereon.

Fig. 3 is a fragmentary composite sectional plan of the central portion of the cover.

Fig. 4 is a fragmentary sectional plan of the same showing details of the structure.

Figs. 5, 6 and 7 are, respectively, cross'sectional views of the cover as shown in Fig. 1 on lines 5--5, 6-6 and 7-7.

The body of the cover is preferably formed of two overlapping circular sheets of fabric 1 and 2 with a peripheral reinforcing strip 3 bent inwardly at 4 and 5 over and extending entirely around the sheets 1 and 2 and stitched thereto at points 6, 6 etc. (See Figs. 1 and 7).

The body members 1 and 2 are cut on radial lines 7 and 8 from the axis thereof and said lines diverge as shown in Fig. 1.

Flaps 9 and 10 are sewed to the radial edges of the sheets 1 and 2 at points 11 and 12. Each of said flaps comprise two thicknesses 13 and 14 of substantially heavy fabric such as canvas, which overlap the radialedges of the sheets 1 and 2, as shown in Fig. 5, and said thicknesses are additionally stitched together at points 15 near their outer edges. Thus the flap 10 substantially overlaps the flap 9 when the cover is operatively positioned on the extractor.

A central opening 16 is provided in the cover around which the cover is reinforced so as to withstand the strains of constant use at high rotative speeds. The opening 16 is for the purpose of receiving the vertical shaft 17 of an extractor 18, which has a rotatable receptacle 19 housed within the extractor 18 and provided with a detachable annular metallic ring 20. The cover is reinforced around the opening 16 by means of a plurality of stranded cords, preferably arranged in pairs, as shown in Fig. 6. I have found that usually four cords formed of stranded cotton of approximately 1A in diameter are suiiicient to properly reinforce the cover. Accordingly I have shown in Fig 6 a pair of such cords 21 and 22 disposed on one side of vthe cover, and another pair of similar cords 23 and 24 oppositely` positioned on the other side of the cover. Each of said pairs of cords are preferably separately wrapped and attached to the body of the cover.

To this end I provide two separate but similar sheets of material 25 and 26 which overlap the outer surfaces of the body members 1 and 2, and as shown in Fig. 3, are cut into stellate form so as to provide a plurality of triangular or pointed portions 27, 27 in the spaces corresponding to the opening 16.

Each pair of cords is positioned one within the other in circular form over the opening 16 and the pointed portions 27 are then bent inwardly around the pairs lof cords and thence downwardly over the sheets 25 and 26 on which the portions 27 are formed. When the cords21, 22, 23 and 24 are thus positioned around the opening 16 on the cover a plurality of straps, as at 28, 28 etc. of the same material of which the cover is made are extended radially around the cords-overlying the portions 27 so that their ends 29 and 30 will overlap each other and the two overlapped ends of each of the members 28 will also overlap the reinforcing sheets 25 and 26, as shown in Fig. 6. y

It will be noted that the members 28 are overlapped substantially at their edges, as shown in Figs. 1 and 3, so that the corded opening 16 of the cover is reinforced with a plurality of thicknesses at all points around the shaft 17.

After the wrappings just described have been properly positioned a pair of annular reinforcing. members 31 and 32 of similar form and size are positioned on opposite sides of the several thicknesses of materials and all of the several thicknesses are stitched together permanently at points 33, 34,` 35, 36 and 37.

It will be observed by reference to Fig. 4 that the ends 38 of all of the cords 21, 22, 23 and 24 are fringed and turned outwardly from the opening 16 for a distance of several inches so that whenv the several thicknesses of material are stitched together with the cords in proper position the fringed portions will be also stitched to the fabric and will thus prevent the movement of the cords on the cover.

The formation of the cover as shown and described herein renders reinforcement by leather or material other than canvas of which the cover is made unnecessary, thereby reducing weight and unnecessary stiffness.

It will be understood that in a cover of this character for use on an extractor, the receptacle of which rotates at a very high speed, it is necessary to provide a cover formed of fabric so that the articles of clothing Within the receptacle 1,9 will not be chafed, abraded or torn by contact therewith. Therefore, it is necessaryto provide a substantially flexible cover having sufficient rigidity at its outer and inner edges to withstand the strains of centrifugal force set up by the high rotative speed of the extractor.

A cover constructed in accordance with my improvements with the flaps 9 and 10 substantially overlapped obviates the necessity for attaching the ends of the cover together, as in other types of flexible covers, for the reason that when the cover, as seen in Fig. 1 with the flap l0 overlying the flap 9, is rotated in a counter-clockwise direction the flap 10 would not tend to be displaced from its position relative to flap 9. As a matter of fact the rotation of the cover as stated would tend to draw the naps 9 and 10 into more perfectly overlapped positions.

'Ihe provision of a plurality of flexible cords 2l, 22', 23 and 24 wrapped and attached to the cover as shown and described provides ample rigidity at the center of the cover around shaft 1'7 and yet sufficient flexibility to permit the ready attachment of the cover to and its removal from an extractor.

Other advantages of my cover will appear to those familiar with the use and operation of extractors of the character shown and described.
